INTRODUCTION

The method is used for the determination of the mass concentration of inorganic anions: chlorate, perchlorate, and chlorite in drinking water including bottled water by capillary electrophoresis.

MEASUREMENT METHOD

The method is based on water test processing cation exchanger in the H-form, separation, identification and determination of mass concentration of chlorate, perchlorate, and chlorite ions by capillary electrophoresis. Identification and quantitative determination of the analyzed anions is performed by indirect detection measuring UV absorption at 266 nm wavelength.
